Hi Issabella, welcome to Steemit. Probably you have a lot of questions about it and the easiest way to get proper answer is from reading the Official website FAQ: (https://steemit.com/faq.html).

I'm a cat person too. My cat just came out of nowhere and live in my house like a hotel. He travels often than me and came back once a while just to greet before his next journey.

Have fun exploring and posting your experiences in Steemit. Cheers!
